Background: The TRH receptor (TRHR) is a G-protein coupled receptor activated by hypothalamic TRH. In thyrotropes, TRH-TRHR signalling controls synthesis, secretion and bioactivity of TSH. Human TRHR defects are extremely rare, and only three cases are known with central hypothyroidism and short stature as variable presenting feature.Objective and hypotheses: Phenotypical characterization of a family with suspected central hypothyroidism and inv...

Background: Imprinted genes are known to regulate fetal growth and a ‘parental conflict’ model predicts that paternally and maternally expressed imprinted genes promote and inhibit fetal growth, respectively. GNAS is a complex imprinted locus with multiple oppositely imprinted gene products. Maternal, but not paternal, G(s)alpha mutations lead to obesity in pseudohypoparathyroidism type IA (PHPIA). However, the disorder rarely causes severe obesity in infancy as pred...
